[0001] The present invention relates to a device for adjusting adisplay, which supports a display such as CRT for personal computer or atelevision set, a liquid crystal display, a plasma display or a displayutilizing LED in a manner so as to freely adjust the angle of thedisplay.

BACKGROUND ARTS

[0002] In recent years, a display for displaying an image such as for apersonal computer system or a television set has been intended to belight weight. Such a type of the display is mounted in front of a framebase possessed by a device for supporting a display in such a manner asto freely adjust the angle, whereby the direction of the display can bechanged to meet the favorite of a user.

[0003] As an example of the device for supporting a display, anelevating device for ascending or descending a liquid crystal monitor asdisclosed in Japanese Utility Model No. 3063920. As shown in FIG. 11,the elevating device for ascending or descending a liquid crystalmonitor possesses a first supporting mechanism 201A which rotatablysupports a liquid crystal 300 around a center axis O at the angel of 90°in the rotating direction X2, and a second supporting mechanism 201Bwhich rotatably supports a liquid crystal 300 around a traverse axis O1in vertically tilting direction X3 in front of a frame base 200.

[0004] However, the elevating device for ascending or descending aliquid crystal monitor disclosed in Japanese Model disclosed abovecannot rotate and adjust the monitor in horizontal tilting direction atthe rotation around the vertical axis (not shown), unless the frame base300 itself rotates in the horizontal direction.

[0005] In addition, since the first supporting mechanism 201A and thesecond supporting mechanism 201B are separately assembled, the number ofparts making up them is increased according to the increasing of thedirection to be adjusted, making it difficult to suppress the increasingof the number of the parts.

[0006] Also, the first supporting mechanism 201A is provided at one sideof a holing arm 202, which makes up the second supporting mechanism201B, and the other side of the holding arm 202 is rotatably supportedon an upper portion of the frame base 200. Moreover, since the traverseaxis O1, which becomes the center P of rotating the liquid crystalmonitor 300 in the vertically tilting direction X3, resides at abackward portion of the liquid crystal monitor 300 far from the liquidcrystal monitor, even if the user is intended to rotate the liquidcrystal monitor 300 to a slight angle, the actual movement distancetowards vertically tilting direction X3 becomes unduly large.Consequently, the adjustment of the frame base 200 in the heightdirection is required every the adjustment of the liquid crystal monitor300 in the vertically tilting direction X3.

[0007] Moreover, depending up the direction of the liquid crystalmonitor 300, the center G of the gravity and the traverse axis O1 aresometimes tilted with each other. For this reason, the force of the userfor adjusting the direction of the liquid crystal monitor is not alwaysconstant. Also, if the liquid crystal monitor 300 is somewhat heavy, theliquid crystal monitor 300 can be fitted in a stable manner only withdifficulty unless an additional part such as a spring is provided.

[0008] Furthermore, when vibration occurs, the position of moving theliquid crystal monitor 300 is sometimes changed with ease.

[0009] An object of the present invention is, therefore, to make aconstruction which is a simple construction having a reduced number ofparts and which makes it easy to adjust the movement of the display inthe 90° revolution direction, a vertically tilting direction andhorizontal direction at a substantial constant position. Particularly,the object of the present invention is to minimize the movement distanceat the time when the display is moved in a vertically tilting direction.Furthermore, the object of the present invention is to make the user toadjust the display always at a constant operation force and not to bringabout displacement when vibration or such occurs.

[0040] On the other hand, the device H for adjusting a direction of adisplay possesses an elevating member 7 in the height direction X1. Onan upper portion of the elevating member 7 are provided four mountingstands 7A, 7A, . . . , to which the display mounter 1 is fit. Theelevating member 7 is also provided on a frame base 7B in a manner offreely ascending and descending, and a spiral spring (not shown) isprovided within the frame base 7B. The spiral spring is provided at aposition where it is wound according to the descending the elevatingmember 7, and is applied to a resilient force to the elevating member 7from a lower direction so that the resilient force becomes substantialconstant regardless of an amount of winding. Moreover, the floor panelof the frame M can be rotated in the horizontal direction, and thehorizontal rotation of the floor panel makes it possible to circulatethe frame M in the vertical direction.

[0041] Subsequently, the base member 2 has a base body 21 and a spacer22, both made of a resin. At the center of the front side of the basebody 21, an inserting projection 23 having a substantial rectangularshape viewing from the front side is formed, and a base stand 24 havinga circular shape viewing from the front side is provide around theinserting projection 23. The inserting projection 23 of the base body 21and the front face of the base stand 24 have the same spherical curve,so that the rear face of the spacer 22 is supported by these insertingprojection 23 and the front face of the base stand 24.

[0042] Furthermore, between the inserting projection 23 and the basestand 24, ribs R and R for imparting strength are provided as shown inFIG. 3. On a rear portion of the base body 21, four bolt mounters 25, 25. . . having bolt pores formed thereon are provided. The bolt mounters25, 25 are provided on corresponding portions of mounting stands 7A, 7A,. . . provided on an upper portion of the elevating member 7,respectively.

[0043] An inserting hole 26 as shown in FIG. 3 is formed at a center ofthe base body 21. The inserting hole 26 has a circular shape viewingfrom the front side, and a nut 30 is provided on a rear portion thereofvia a washer W.

[0044] The spacer 22 described above has a pedestal 27 and a rear sideinserting portion 28. The front face of the pedestal 27 of the spacer 22has a spherical shape and the center thereof is formed so that thereceiving surface 27 can be largely opened. On the other hand, the rearside inserting portion 28 of the spacer 22 has a substantial rectangularshape viewing from the front side and has a figure similar to theinserting projection 23 of the base body 21 smaller than the later asthe thickness of the inserting projection 23. The rear side insertingportion 28 of the spacer 22 is inserted into the inserting projection 23of the base body 21 to fit the spacer 22 to the base body 21.

[0045] The cap supporting member 3 has a cap body 31 and a rear sideinserting portion 32. The cap body 31 makes up a part of a sphericalshape having the substantially same curvature as that of the receivingface 27A of the pedestal 27 of the spacer 22, and has verticallyarranged two wall portions 33A and 33B for a stopper making up a part ofthe stopper 6 and six reinforcing ribs 34, 34, . . . provided in frontthereof. Each of these wall portions 33A and 33B for a stopper isarranged so as to extend in the vertical direction and is provided so asto project towards the front of the member 5 for regulating an angle. Onthe other hand, the reinforcing ribs 34, 34, . . . are provided so as toslightly project from the front surface of the cap body 31. Furthermore,at a substantially center of the cap body 31, a spring receiver 35 isformed. The spring receiver 35 is formed in the state that it issurrounded by projections 36 each having a circular shape viewing fromthe front side, and the projection 36 is provided so as to slightlyproject from the reinforcing rib 34 respect to the front surface of thecap body 31.

[0046] The rear side projecting portion 32 provided on a rear surface ofthe cap body 31 has a cylindrical shape having an external diametersubstantially the same as an inner surface of the inserting hole 26formed at the center of the base body 21, and has a through hole 38 forbolt through which a bolt 8 is bored formed at a central portionthereof. The rear side projecting portion 32 is inserted into an openingformed on the center of the pedestal 27 of the spacer 22, and isinserted into the inserting hole 26 formed at the center of the basebody 21.

[0047] The flange 4 has a panel portion 41 and a spherical portion 42 atthe center of the panel portion 41 having a concave formed on a rearside. The panel portion 41 of the flange 4 has a rectangular shapeviewing from the front side, and through holes 43, 43, . . . are formedof the four corners thereof. The spherical portion 42 of the flange 4makes up a part of the spherical surface having the substantially samecurvature as that of the receiving face 27A and the cap body 31 of thecap supporting member 3. At a central portion of the spherical portion42, an opening 44 is largely formed into which the rear side projectingportion 32 of the cap supporting member 3 is inserted. Furthermore, thespherical portion 42 of the flange 4 is sandwiched between the receivingface 27A of the pedestal 27 of the spacer 22 and the cap body 31 of thecap supporting member 3 in a slidable manner. By such a construction,the flange 4 is held and fitted in the state that it can be rotatedaround a center axis O at the angel of 90° in the rotating direction X2,around a traverse axis O1 in vertically tilting direction X3, and arounda vertical axis O2 in horizontal tilting direction X4 (see FIG. 4).

[0048] In this case, as shown in FIG. 6, the center axis O, the traverseaxis O1 and the vertical axis O2 are defined as ideal axes passingthrough an origin, assuming the center P of the rotation of the flange 4as the origin, which will be utilized in the following description.

[0049] In front of the flange 4, the member 5 for regulating an angle isprovided. The member 5 for regulating an angle has a plate-from mainbody 51 having substantially the same sides as those of the panel 41 ofthe flange 4. Through holes 52, 52, . . . are formed on the positionscorresponding to the through holes 43, 43, . . . formed on the fourcorners of the panel portion 41 of flange 4. Furthermore, Bolts B, B, .. . are inserted into the through holes 43, 43, . . . formed on theflange 4 and the through holes 52, 52, . . . formed on the member 5 forregulating an angle, and these bolts B, B, . . . are screwed into boltpores (not shown) formed on rear surfaces of the display D shown in FIG.4. By such a construction, flange 4 and the member 5 for regulating anangle are fixed onto the display D in a co-screwing state.

[0050] In addition, four projections 53A, 53B, 53C, and 53D for astopper, which make up a part of the stopper 6 and which projectbackward, are formed on the rear surface of the member 5 for regulatingan angle. These projections for a stopper 53A to 53D are formed so as tohave the same projection amount, and as shown in FIG. 3, each of theirlengths are set so as to reach the wall portions 33A and 33B for astopper formed on a front surface of the cap supporting member 3 and notto reach the reinforcing rib 34. These projections for a stopper 53A to53D are brought into contact with the wall portions 33A and 33B for astopper, respectively, whereby the rotation of the member 5 forregulating an angle and the display D held by the member 5 forregulating an angle as shown in FIG. 4 and FIG. 5. This makes itimpossible to revolute them any more. The stopper 6 is composed of wallportions 33A and 33B for a stopper provided on the cap supporting member3 and these projections 53A to 53D for a stopper provided on the member5 for regulating an angle make up the stopper 6, which regulates therotation range.

[0051] As shown in FIG. 3, the bolt 8 is screwed into the nut 30provided on a rear side of the base body 21. The bolt 8 has a headportion 8A having a large diameter and a screw portion 8B formed on theedge portion. The screw portion 8B is screwed into the nut 30. The rearsurface of the head portion 8A is in a plate form, and a coil spring 9is intervened between the rear surface and the spring receiver 35 of thecap supporting member 3. The coil spring 9 is fitted in a slightlycontracted state.

[0052] Here, since the bolt 6 is screwed into the nut 30, the coilspring 9 is in the fixed state fixed to the base member 2. For thisreason, the coil spring 9 will expand due to the reverse force to thehead portion 8A. At this time, by the resilient force of the coil spring9, the cap body 31 of the cap supporting member 3 is applied to theresilient force in the direction of the spacer 22. By the application ofthe resilient force to the cap body 31 in the direction of the spacer22, the spherical portion 42 of the flange 4 positioned between the capbody 31 and the spacer 22 is sandwiched.

[0053] As described above, the flange 4 is held by the cap supportingmember 3 in a manner that the flange 4 can be slid in any of thedirections center axis O at the angel of 90° in the rotating directionX2, the traverse axis O1 in vertically tilting direction X3, andvertical axis O2 in horizontal tilting direction X4 as shown in FIG. 2and FIG. 3.

[0054] The device H for adjusting a display having construction asdescribed above according to the present invention will now bedescribed.

[0055] In the device H for adjusting a display, the flange 4 issandwiched between the receiving face 27A of the spacer 22 and the rearsurface of the cap supporting member 3, and the display D is held by theflange 4 via the member 5 for regulating an angle. The flange 4 can beslid along the receiving face 27A. By such a structure, as for thedisplay D fitted to the flange 4, the revolution around the center axisO at the angel of 90° in the rotating direction X2, that around thetraverse axis O1 in vertically tilting direction X3, and that around thevertical axis O2 in horizontal tilting direction X4 can be performed byonly one display mounter 1.

[0056] Subsequently, the revolution of the display D around the centeraxis O at the angel of 90° in the rotating direction X2 will now bedescribed. As shown in an ideal line (double dot line) in FIG. 5, anyone of the projections 53B and 53D for a stopper of the member 5 forregulating an angle is brought into contact with any of the wallportions 33A and 33B for a stopper to regulate the movement thereof. Itis assumed that at this time, the display D has been turned sideways. Inorder to turn the display D into the lengthwise direction from thisstate, when the display D is rotated clockwise around the center axis Oshown in FIG. 2 to FIG. 4, the member 5 for regulating an angle is alsoturned around the center axis O at the angel of 90° in the clockwiserotating direction X2 as shown in FIG. 5. When the display D is rotatedclockwise at 90°, now any one of the projections 53A and 53C for astopper of the member 5 for regulating an angle is brought into contactwith any of the wall portions 33A and 33B for a stopper to regulate themovement thereof. At this time, the flange 4 is rotated together withthe member 5 for regulating an angle, and the movement is regulated justat the time when they are rotated at 90°. This makes it possible to turnthe display which is in the sideway into the lengthwise way.

[0057] Next, the revolution of the display D around the traverse axis O1in vertically tilting direction X3 will now be described. As shown inFIG. 6, the flange 4 can be rotated around the traverse axis O1 shown inFIG. 2 to FIG. 4 relative to the base member 2 and the cap supportingmember 3, but the rotation range thereof is regulated. Specifically, bythe rotation of the display D around the traverse direction O1, when theflange 4 and the member 5 for regulating an angle is rotated around thetraverse direction O1 counterclockwise shown in FIG. 5 from the statewhere they are positioned at the center shown in the real line to betilt them downwardly, a lower rear surface of the body 51 of the member5 for regulating an angle is brought into contact with the wall 33B fora stopper. Also, when the flange 4 and the member 5 for regulating anangle is rotated around the traverse direction O1 clockwise shown inFIG. 5 to be tilt them upwardly, an upper rear surface of the body 51 ofthe member 5 for regulating an angle is brought into contact with thewall 33B for a stopper. This makes it possible to turn the direction ofthe display D in vertically tilting direction X3.

[0058] Here, when the body portion 51 of the member 5 for regulating anangle is directed downwardly, the projection 53D for a stopper residingabove the body portion 51 is never come into contact with the wall 33Afor a stopper. However, when the projection 53D for a stopper residingabove the member 5 for regulating an angle is not brought into contactwith the wall 33A for a stopper, the projection 53B for a stopperresiding below the member 5 for regulating an angle is come into contactwith the wall 33B for a stopper residing below the cap supporting member3. In this state, there is a fear that the projection 53B for a stopperresiding below the member 5 for regulating an angle is bumped againstthe reinforcing rib 34 of the cap supporting member 3. However, as shownin FIG. 6 as a broken line, the length of the projection of thereinforcing rib 34 is set to be short, i.e., set so that even if theprojection 53B for a stopper comes the closest to the reinforcing rib 34does not bump against the projection 53B for a stopper. Similarly, it isset that other projections 53A, 53C, and 53D come the closest to thefront surface of the cap body 31, they do not bump against the frontsurface of the cap body 31.

[0059] As described above, the body portion 51 of the member 5 forregulating an angle is directed downwardly, the rotation range in anupper direction of the member 5 for regulating an angle and that of theflange 4 can be regulated by means of the projection 53B for a stopperresiding below the member 5 for regulating an angle and the wall 33B fora stopper. Conversely, when the body portion 51 of the member 5 forregulating an angle is directed upwardly, the projection 53B for astopper residing below the member 5 for regulating an angle is not comeinto contact with the wall 33B for a stopper, but the projection 53D fora stopper residing above the member 5 for regulating an angle is comeinto contact with wall 33A for a stopper residing above the capsupporting member 3. As described above, when the body portion 51 of themember 5 for regulating an angle is directed upwardly, the rotationrange in a lower direction of the member 5 for regulating an angle andthat of the flange can be regulated by means of the projection 53D for astopper residing above the member 5 for regulating an angle and the wall33A for a stopper of the cap supporting member 3.

[0060] At this state, for example, the display D is assumed to be alengthwise direction, if the display D resides in a width direction, asshown in FIG. 5 as a real line, the projection 53A for a stopper isplaced on an upper portion and the projection 53C for a stopper isplaced on a lower portion. By functions similar to those of theprojections 53D and 53 for a stopper, the rotation of the display D canbe regulated. What is more, by placing the stopper at the position wherethe display D is rotated just at 90°, the display D can easily be set inboth the lengthwise direction and the width direction.

[0061] In the rotation of the display D shown in FIG. 4 around thevertical axis O2 in horizontal tilting direction X4, in the case whereno stopper is provided, the rotation is similar to the rotation of thedisplay D around the traverse axis O1 in vertically tilting directionX3. However, in the case where the projections for a stopper isprovided, the rotation of the display D around the vertical axis O2 inhorizontal tilting direction X4 is regulated.

[0062] Consequently, in the device H for adjusting a direction of adisplay according to the present invention, the rotation of the displayaround a center axis O at the angel of 90° in the rotating direction X2,that around a traverse axis O1 in vertically tilting direction X3 andthat around a vertical axis O2 in horizontal tilting direction X4, canbe performed only by sandwiching the flange 4 by the base member 2 andthe cap supporting member 3 in the display mounter 1. Consequently,unlike the prior art in which supporting mechanisms are separatelyprovided in order to meet all the rotation of the display D, a number ofparts can be decreased.

[0063] Also, in the device H for adjusting the direction of a displayaccording to the present invention, the center P of the rotation of theflange 4 (see FIG. 10), which slides along the receiving face 27A of thepedestal 27 of the spacer 22, in the vertically tilting direction X3 ispositioned in front of the receiving face 27A. For this reason, theflange 4, the member 5 for regulating an angle and the display D arerotated around a point positioned in front of the receiving face 27A asa center. By such a construction, when the display is rotated around thevertically tilting direction X3, the movement distance can be reduced incomparison with the prior art.

[0064] Furthermore, since the center P of the rotating the flange 4 ispositioned in front of the receiving face 27A, the center P of therotation can be substantially accorded with the center of the gravity ofthe display D. Specifically, In this embodiment, the center P of therotating the display D in the vertically tilting direction X3 isaccorded with the center of the gravity of the display D.

[0065] As described above, since the center P of the rotating thedisplay D in the vertically tilting direction X3 is accorded with thecenter of the gravity of the display D, the center of the gravity of thedisplay D can be substantially unchanged even when the display isrotated. Consequently, the user can rotate the display D always bysubstantially the same force, and the display D can effectively beprevented from being felt down towards the front side.

[0066] Preferred embodiments of the present invention have beendescribed, but the present invention is not restricted thereto. Forexample, in order to prevent the display from being rotated due tovibration or such when the display is in the lengthwise or widthdirection, a ball click for imparting so called click feeling may beprovided on the flange and the base member.

[0067] Also, the parts described above may be produced in a unifiedstate to further decrease the number of parts. It is noted thatmaterials for each parts may be freely selected, for example, part of orall of the parts may be made of, e.g., a metal, a resin, a reinforcingplastic, or such.

[0068] Subsequently, a second embodiment of the present invention willbe described in detail by referring to the drawings. FIG. 7 is anexploded perspective view showing the device for adjusting a directionof a display according to the second embodiment partially showing themain portions, FIG. 8 is a front view thereof, FIG. 9 is a plane viewthereof, and FIG. 10 is a perspective view thereof.

[0069] As shown in FIG. 7, a device H′ for adjusting a direction of adisplay according to the present invention has a base member 101, spiralsprings 102 and 102 and an elevating member 103. Spacers 104 and 104 arefitted to both ends of the elevating member 103, a center guide member105, which fixes the height position of the elevating member 103relative to the base member 101 is provided at the central position ofelevating member 103 in the height direction.

[0070] The base member 101 has a pedestal 111 and a holder 112. acircular rotation table 113 shown in FIG. 9 as a broken line is providedwithin the pedestal 111 so as to be able to rotate in the verticaldirection. The holder 112 is ma de of a metal, stands along one end ofthe pedestal 111, and guide portions 114 and 115, which form slidegroove extending towards a vertical direction, are proved on both endsof the holder 112 viewing from the front side. The space between theguide portions 114 and 115 is opened at the front side, and has a centerguide portion 116 for connecting the guide portions 114 and 115 providedat a rear side. The center guide portion 116 of the holder 112 is formedso that it is bent to slightly project toward a front side, and has athrough hole 117 formed on an upper side thereof. As described above,since the center guide portion 116 of the holder 112 is formed into ashape so as to project towards a front side, and since it is guided andsupported by the center guide member 105, it prevents the device H′ foradjusting a direction of a display from being felt down towards thefront side due to the weight of the display D and from being undulymoved towards a horizontal direction.

[0071] Spiral springs 102 and 102 are provided within the guide portions114 and 115, respectively, and one ends of the spiral springs 102 and102 are fixed onto inner sides of the guide portions 114 and 115 bymeans of fixing members 121 and 121. The spiral springs 102 and 102 arefitted so that the winding portions thereof are wounded following thedescending of the elevating member 103. Also, when the winding portionsof the spiral springs 102 and 102 are wounded as described above, theresilient forces thereof are directed towards a direction that theelevating member 103 is pushed up. In this case, the resilient forces ofthe spiral springs 102 and 102 are always at substantial constantregardless of an amount of winding.

[0072] The elevating member 103 is made of a metal, and has insertingportions 131 and 132 which are inserted into the guide portions 114 and115 of the base member 101, respectively provided thereon. Theseinserting portions 131 and 132 of the elevating member 103 are insertedinto the guide portions 114 and 115 of the base member 101 so that theelevating member 103 may be relatively moved toward the verticaldirection (Z direction in FIG. 8) relative to the base member 101. Thespace between the inserting portions 131 and 132 of the elevating member103 is opened at the rear side, and is connected at a front side to acentral portion 133 formed so that it is bent to slightly project towarda rear side. The central portion 133 has the display mounter 106provided at an upper portion, and the display mounter 106 is fitted sothat the display D can be mounted as shown in FIG. 10.

Specifically, when the spacers104 and 104 are inserted into the inserting portions 131 and 131 of theelevating member 103, the winding portions of the spiral springs 102 and102 are come into contact with the bottom portions 143 and 143 of thespacers 104 and 104 to support the elevating member 103.

[0074] Furthermore, groove portions 146 and 146 are provided on outsidesof the spacers 104 and 104, and deforming portions 147 and 147projecting inwardly are unified at lower portions of the groove portions146 and 146. The groove portions 146 and 146 of the spacers 104 and 104are configured so that expanding portion of the spiral springs 102 and102 expanded when the elevating member 103 descends are inserted. At thetime when the elevating member 103 is inserted into the guide portions114 and 115 of the base member 101, the spacers 104 and 104 are comeinto contact with the guide portions 114 and 115, and they are guided bythe guide portions 114 and 115 to vertically move together with theelevating member 103.

[0075] Upper portions potions 142 and 142 of the spacers 104 and 104 arerotatably fitted to the elevating member 103 by means of shafts 148 and148 so that they can be waved in the X1 direction and X2 direction shownin FIG. 7. The deforming portions 147 and 147 of the spacers 104 and 104are come into contact with the side surfaces of the inserting portionsof the elevating member 103 and apply resilient forces so that thespacers 104 and 104 are slightly pushed up to the outer side. In thiscase, since the spacers 104 and 104 are made up of a resin, for example,even if the guide portions 114 and 115 are made of a metal, generationof uncomfortable sound at the time of rubbing metals and galvaniccorrosion due to the contact with metals can be prevented.

[0076] Furthermore, the center guide member, 105 possesses a square nut151, a slide stopper 152, a bolt 153, and a packing spacer 154. Thesquare nut 151 is fixed on the rear surface of the center guide portion116 of the holder 112, and a bolt pore 151A is formed on the centralportion thereof. The slide stopper 152 is made of a resin and isprovided on a front side of the elevating member 103, and has a body152A and an inserting portion 152B. A through hole 152C for a bolt whichis pierced between the body 152A and the inserting portion 152 is formedon the slide stopper 152B. The inserting portion 152A of the slidestopper 152 has a cross-sectional shape substantially similar to that ofthe shape of the opening of a pore 134 for inserting a slider formed inthe elevating member 103. An inserting portion 152B of the slide stopper152 is inserted into the pore 134 for inserting a slider.

[0077] The bolt 153 of the center guide member 105 has a head portion153A and a screw portion 153B. The screw portion 153B of the bolt 154 isinserted into the through hole 152C for a bolt form on the slide stopper152 from a front side, and passed through the pore 134 for inserting aslider of the elevating member 103, and is screwed into the bolt pore151A formed on the square nut 151. By the clamping force of the bolt153, the elevating member 103 and the base member 101 are sandwiched bythe square nut 151 and the slide stopper 152 so as to prevent theelevating member 103 from being felt down toward the base member 101 andto regulate the horizontal movement of the elevating member 103.

[0078] The packing spacer 154 is made of a resin and as shown in FIG. 9,it is provided between the elevating member 103 and the base member 101.On the packing spacer 154, a through hole 154A for a bolt having anopening with the shape substantially the same as the opening of thethrough hole 117 formed on base member 101 is formed. The packing spacer154 is positioned so that the through hole 154A for a bolt is overlappedwith the through hole 117 of the base member 101. By placing the packingspacer 154 between the base member 101 and the elevating member 103 asdescribed above, generation of uncomfortable sound at the time ofrubbing metals and galvanic corrosion due to the contact with metals canbe prevented.

[0079] To the device H′ for adjusting a direction of a display havingsuch a construction is fitted, for example, a display D as shown in FIG.10. The device H′ for adjusting a direction of a display is used by theuser in the state where the height is adjusted to the position desiredfor the user depending on the condition. In the device H′ for adjustinga direction of a display, the elevating member 103 is inserted into theguide portions 114 and 115 of the base member 101. At this time, theinserting portions 131 and 132 of the elevating member 103 slightly pushup the deforming portions 147 and 147, to apply the reproducingresilient force to the deforming portions 147 and 147. For this reason,the spacers 104 and 104 are pushed up in an elastic manner to the sideportions of the guide portions 114 and 114 (X1 direction and X2direction in FIG. 7) By such a construction, at the time of ascending ordescending the elevating member 103, the elevating member 103 slides tothe guide portions 114 and 115 by the friction depending upon thereproducing resilient force of the deforming portions 147 and 147. Also,as described above, the clearance between the base member 101 and theelevating member 103, i.e., between the guide portions 114 and 115 ofthe base member 101 and the inserting portions 131 and 131 of theelevating member 103, is removed to support smooth vertical movement ofthe elevating member 103 relative to the base member 101.

[0080] It is noted that the elevating member 103 as described above isfreely operated as a rule, but by adjusting the bolt 153 of the centerguide member 105 the operation force of the elevating member 103 may belightened or by tightly clamping the bolt 153, the elevation of theelevating member 103 may be regulated.

[0081] Also, the parts described above may be produced in a unifiedstate to further decrease the number of parts. It is noted thatmaterials for each parts may be freely selected, for example, part of orall of the parts may be made of, e.g., a metal, a resin, a reinforcingplastic, or such.
